Install Java SDK in Linux-Redhat as 5

1. Download the corresponding Java SDK version from the sun Portal

I downloaded the jdk-6u6-linux-i586-rpm.bin version.

2. grant permissions to the downloaded file

1. Generally, the root permission is required. Enter Su at the $ prompt and enter the password to enter the root mode. Prompt #

2, # chmod 755 jdk-6u6-linux-i586-rpm.bin

3, #./jdk-6u6-linux-i586-rpm.bin

4. # rpm-IVH jdk-6u6-linux-i586-rpm

3. Set Environment Variables

There are three ways to modify the network

1. Modify/etc/profile

2. Modify. bashrc

3. directly modify it in Shell

I have tried either of the three methods, but none of them are successful. And then solved with the help of friends.

The modification method is as follows:

$ VI. bash_profile

Add the following to this file:Code:

# Set Java environment
Export java_home =/usr/Java/jdk1.6.0 _ 06
Export classpath =.: $ java_home/lib: $ java_home/JRE/lib:/usr/Java/jdbc
Export Path = $ java_home/bin: $ java_home/JRE/bin: $ path

Restart.

In addition, when a file is created using VI during the test, you must grant the read/write permission to the file to modify the file. The command is as follows:

Chmod R + W file name
